Question

between 9 p.m. and 6:36 a.m. the water level in a swimming pool decreased by 8/25 in. Assuming that the water level decreased at a constant rate, how much did the water drop each hour

Answer 1

≈0.033 in per hour

Explanation:

First, calculate the time between 9pm to 6:36am

There are 9 hours and 36 minutes.

then convert 36 minutes into hours

36/60 = 0.6 hour

so, 9.6 hours

then divide the total drop of water by 9.6

8/25 ÷ 9.6 = 0.03333....
